WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 343,895, dated June15,1886.

Application filed May 13, IFBG. Serial No. 202,081.

To all whom it may concern.-

Be it known that I, GEORGE DENNY, a citizen of the United States ofAmerica, residing at La Gygne, in the county of Linn and State ofKansas, have invented certain new and use ful Improvements inWagon-Brakes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain new and useful improvements inwagon-brakes and means for operating the same; and my invention consistsin the construction and combination of the parts, as will be hereinafterfully set forth,

which are secured forwardly-diverging bars B B, to which the hounds Gare attached, said hounds being provided near the rear end of the reach0 with a crossbar, c, which is rigidly attached thereto, and serves as abrace for the ends of the bars B B. By this means the hounds, reach, andbars B B and the rear axle are rigidly connected to each other.

To the upper side of the bars B B is journaled a rock-shaft, D, which isprovided at one side with a downwarly-bent end, (I. The opposite end ofthis rock-shaft D is key-ended, and is embraced by a lever, E, whichlever is secured thereto by a suitable nut, 6. At the right-hand side ofthe vehicle-frame, to the rear axle, a bent bar, F, is attached by meansof the bolt f,.said bent bar having a nearly-horizontal portion, f, fromwhich extends 21 segmental curved portion, F, which is provided withserrations g. The lower end of this bar and the segmental portion isprovided with a perforation, through which passes a brace-bar, 9, saidbrace-bar first passing through a per- {oration in the horizontalportion F, from (No model.)

thence through-a washer, and then through a perforation in the end ofthe segmental portion F. The horizontal portion f of the bar F isprovided with a central opening, through which the rock-shaft passes. Bythe means just described the bar F is held securely in place.

The lever E is rigidly secured to the rockshaft D, and is provided atitsupper end with a rearwardly-projecting portion, E, which is providedwith a curved slot, and to its lower portion is attached a link, G,which connects the same to the pivoted bars H H of the brake mechanism.The opposite pivoted bar H is connected by alink, G, to the dependingportion d of the rock-shaft, which is on a line with the end of thelever E.

The brakelever E is provided at its rear edge, a slight distance abovethe nut 6, with a pocket, 72, within which is secured a spring, h, saidspring bearing upon a pivoted pawl or locking-dog, I, said locking-dogbeing attached to the square bolt 2', which passes through the lever E,and also through the end of the lever J, and from thence through ashortlink, j, said link being pivotally attached to the rock-shaft D. It willthus be seen that when the short lever J is moved the dog will be turnedtherewith, as the perforation in saidv lever is squared so as tocorrespond with the configuration ofthe bolt. Thus when the short leveris turned down or forced rearwardly it will act upon the pawl or dog soas to release the same from the serrations g of the segmental bar. Theshort lever J, hereinbefore referred to, has a forwardlyextendingslotted portion, J. Above the segmental curved bar F the lever E haspivoted thereto a hand-lever, K, the intermediate portion thereof beingprovided with a slot, through which passes a bolt, 70, said bolt alsopassing through the curved slots in the upper bent ends of the levers Eand J.

. The operation of theportion of my invention hereinbefore described isas follows: When it is desired to put'on the brakes, the hand-lever K ismoved forwardly, which swings the rockshaft D, so as to draw the ends ofthe pivoted bars H rearwardly. The movement of this hand-lever causesthe dog to slide over the serrations g, and will hold the same inposition for further movement. When it is desired to release the brakes,by moving this handlever rearwardly it will engage with the rear end ofthe slot J, so as to throw the dog out of engagement, and thus releasethe brakes. The short hand-lever K is designed especially for operatingthe brakelevers at the rear portion of the vehicle, and when it isdesired that the brake-bars should be operated from the forward portionof the vehicle near the drivers seat, I secure thereto a doublebifurcated bar, K, the ends of which are embraced by a bolt, k, which isattached to the short hand-lever and passes through the slots in theportions E and J of the levers E and J. The forward end of this bar L ispivotally attached to the end of the lever K, the lower end ofwhich ispivotally attached to the wagonbody. When this lever K is movedforwardly, the brakes are put on or forced against the hind wheels, andwhen it is moved rearwardly it will force the bolt it against the rearends of the slots in the bent portions E and J, so as to turn therock-shaftD and release thedog I from the serrated curved bar F.

The bars H H, to which the links G G are attached, are pivotally securedto the hounds by means of bolts Z l, and said bolts arebraced on theirunder sides by crossbars M, which extend to the rear axle. These barsare attached by means of links or straps m to the inner ends of the barsN, which are pivotally secured by means of bolts n to the bars B,and attheir portions through which the bolts n pass they are provided withcurved slots n, which will allow said bars a slight lateral movement, sothat the brake-shoes at the ends of said bars will be held parallel withthe tires of the wheels. The end of the reach 0 is braced to the houndsby a crossbar, as shown, and beneath the same is attached a bolt, 0,which carries a spring, 0, the terminal portions of which bear upon theends of the pivoted bar N, so as to throw said bars outwardly, thusholding said bars normally against the inner sides of the slots a.

By the arrangement hereinbe fore described, by a single lever thebrake-bars and dog can be operated so as to put on or release thebrakes.

Having thus described my invention, I do not limit myself to the preciseconstruction herein shown and described, but reserve the right to modifyor change my invention within the scope of my claims.

What I claim as new, and desire to secure by Letters Patent, ise 1. In awagon-brake, the combination of the shoe carrying b'ars N, provided withcurved slots, the inner end of said bars being attached to pivoted barsH, the outer ends of said bars being provided with links G, which areconnected to a rock-shaft and lever, the parts being organizedsubstantially as shown, and for the purpose set forth.

2. In a wagon-brake, the combination of the pivoted shoe carrying barsN, bars H, pivotally attached thereto and connected at one end to arock-shaft and at the other end to a lever, E, levers K and K, foroperating the rockshaft either from the rear or front portion of thevehicle, substantially as shown,and for the purpose set forth.

3. In combination with a rock-shaft, D, the brake mechanism constructedsubstantially as described, a lever, E, attached to the rockshaft andprovided with a pivoted hand-lever,

K, a pivoted lever, J, with slotted end J, for

releasing a pawl from a bar, F,substantially as shown, and for thepurpose set forth.

4. In combination with a lever, E, for operating the brake-bars, saidlever being rigidly attached to a rock-shaft, a bar, F, provided with acurved serrated portion, g, a pivoted lever, J, carrying at its lowerend a dog, and provided at its upper end with a slotted portion, J, ahand-lever pivoted to the lever E and provided with a bolt, is, whichpasses through the slotted portion G and J of thelevers, aconnecting-bar, L, attached at its forward end to a hand-lever, K, theparts being organized substantially as shown, and for the purpose setforth.

5. The combination, in a wagon-brake, of a rock-shaft, D, rigidlyattached at one end to a lever, E, the opposite end being provided witha downwardly-bent portion, d, a bent bar, F, suitably supported by thewagon-frame and provided with a serrated segmental portion, F, a lever,J, pivotally attached to the lever E, and carrying at its lower end aspringactuated dog, I, the levers J and E being provided at their upperends with opposite bent portionsE and J,through which passes a bolt, 70,attached to the hand-lever K, the parts being organized substantially asshown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE DENNY.
